How to Set an Outlook Mobile Quiet Hours Schedule per Day of Week

The Outlook mobile app for iOS and Android includes a Quiet Hours feature that stops notifications during a set time window. By default, Quiet Hours applies the same schedule to every day of the week. You may want different quiet periods for weekdays versus weekends or a separate schedule for each day. This article explains how to set a per-day Quiet Hours schedule in the Outlook mobile app, covering the steps for both iOS and Android. It also describes the limitations of the feature and what to do if the schedule does not apply correctly.

Overview of Outlook Mobile Quiet Hours

Quiet Hours is a notification management feature built into the Outlook mobile app. When enabled, it suppresses all push notifications, lock screen alerts, and banner notifications for incoming email and calendar events during the defined time window. The feature operates independently of your phone’s system-level Do Not Disturb mode. This means you can receive notifications from other apps while Outlook notifications are silenced.

The Quiet Hours schedule is stored in your Outlook account settings and syncs across devices signed in with the same account. Changes made on an iPhone will apply to an iPad signed in with the same Outlook account, and vice versa. The per-day schedule option is available in Outlook version 4.2406.0 or later on iOS and version 4.2406.0 or later on Android. To check your app version, open Outlook, tap your profile picture, tap the gear icon, and scroll to the bottom of the Settings screen. The version number appears under About.

Steps to Set a Per-Day Quiet Hours Schedule

The following steps apply to both iOS and Android versions of the Outlook mobile app. The interface is identical on both platforms.

1. Open Outlook Settings
   Launch the Outlook mobile app. Tap your profile picture in the upper left corner. Tap the gear icon to open Settings.
2. Go to Notifications
   In the Settings list, tap Notifications. This opens the notification configuration screen.
3. Tap Quiet Hours
   Under the Notifications section, tap Quiet Hours. You see a list of the seven days of the week. Each day shows a toggle switch and the current start and end time.
4. Enable Custom Schedule for a Day
   Tap the toggle switch next to a day so it turns blue. This enables the Custom Schedule for that day. The Start and End fields become editable.
5. Set the Start and End Time
   Tap the Start field. Use the time picker to select the hour and minute when Quiet Hours should begin. Tap AM or PM if your region uses a 12-hour clock. Tap Done or OK. Repeat the same process for the End field. The end time must be later than the start time on the same day. If you want Quiet Hours to span midnight, set the end time to 11:59 PM and the start time to 12:00 AM of the next day. Outlook does not support cross-day Quiet Hours in a single day entry.
6. Repeat for Each Day
   Repeat steps 4 and 5 for each day where you want a separate Quiet Hours schedule. Days without an enabled toggle will use the default Quiet Hours schedule, which is the schedule set on the main Quiet Hours screen before you opened the per-day view. If you have never set a default schedule, days without an enabled toggle will not silence notifications.
7. Save the Changes
   Tap the back arrow in the upper left corner to return to the Notifications screen. Your changes are saved automatically. No separate Save button exists.

Common Mistakes and Limitations

Quiet Hours Does Not Activate on the Scheduled Day

If Quiet Hours does not start at the scheduled time on a specific day, verify that the day’s toggle is enabled. A disabled toggle means the custom schedule is not active. Also check that the device’s system time zone matches the time zone set in Outlook. Open Outlook Settings > General > Time Zone to confirm. If the time zone differs by more than a few minutes, the Quiet Hours start time may appear to trigger at the wrong clock time.

Notifications Still Appear During Quiet Hours

Quiet Hours suppresses only Outlook notifications. If you see notifications from other apps, that behavior is expected. If you see Outlook notifications despite Quiet Hours being active, force close the Outlook app and reopen it. On iOS, swipe up from the bottom of the screen, pause, then swipe up on the Outlook card. On Android, tap the square or recent apps button and swipe Outlook away. Relaunch Outlook and check that the Quiet Hours schedule is still enabled.

Cross-Day Quiet Hours Not Supported

Outlook does not allow a Quiet Hours period that spans across two calendar days in a single day entry. For example, you cannot set Quiet Hours from 10:00 PM Monday to 6:00 AM Tuesday in one entry. To work around this, enable Quiet Hours on Monday from 10:00 PM to 11:59 PM and enable Quiet Hours on Tuesday from 12:00 AM to 6:00 AM. Both days must have their toggles enabled. The two entries together create a continuous quiet block.

Changes Not Syncing to Other Devices

Quiet Hours settings sync through your Microsoft account. If changes made on one device do not appear on another, sign out of Outlook on both devices, then sign back in. On the device where the schedule is correct, open Quiet Hours and tap the back arrow to force a sync. On the other device, close and reopen Outlook. The updated schedule should appear within 60 seconds.

Per-Day Quiet Hours vs Default Quiet Hours: Key Differences

Item	Per-Day Quiet Hours	Default Quiet Hours
Schedule scope	Applies only to the selected day	Applies to all days unless overridden
Configuration location	Settings > Notifications > Quiet Hours > tap a day	Settings > Notifications > Quiet Hours > set time on the main screen
Number of schedules	Up to 7 separate start/end pairs	One start/end pair
Cross-midnight support	Requires two adjacent day entries	Not supported
Sync behavior	Syncs per-day entries across devices	Syncs the single schedule across devices

You can now configure Outlook mobile Quiet Hours with a separate schedule for each day of the week. After setting the per-day schedule, test it by sending a test email to your account during the quiet period. If you need to silence notifications for a longer block that crosses midnight, enable Quiet Hours on both the evening day and the morning day. For a quick way to silence all Outlook notifications immediately without changing your schedule, enable the Focused Inbox filter or turn off the Outlook notification toggle in your device’s system settings.
